why does our nose get stuffy when we have a cold
Answer:
Due to dilation of blood vessels in the sinuses of the nose
Explanation:
Often times, we think our nose gets stuffed up due to the excess mucus in times of cold but it is not always so.
We get stuffed due to the body's homeostasis, a drive to internally control and balance the outside environment.
- During cold, blood vessels dilate so as to allow for more inflow of blood.
- Incoming blood brings in more heat to the body parts.
Answer:ATP, Endergonic, Phosphate group, ATP synthase, Exergonic
Explanation:
1. ATP is the energy currency of the cell. The energy released from the hydrolysis of ATP is use to drive cellular work.
2. ATP are used to drive endergonic reaction. Endergonic reaction are energy requiring hence ATP is hydroxyze to release energy to power endergonic reaction.
3.ATP is formed when a phosphate group is transferred to ADP. Which is an example of endergonic reaction
ADP+Pi+free energy→ATP+H2O.
4. The oxidative phosphorylation of ADP to ATP is catalyze by the enzyme ATP synthase.
5. ATP synthesis is an endergonic reaction in which free energy is needed to phosphorylate ADP to ATP and the reaction is driven by Exergonic reaction.
DNA Replication How DNA Makes Copies of Itself. Before a cell divides, its DNA is replicated (duplicated.) Because the two strands of a DNA molecule have complementary base pairs, the nucleotide sequence of each strand automatically supplies the information needed to produce its partner
Answer:
Biological species.
Explanation:
Various concept like morphology species concept, ecological species concept was introduced by the scientists to explain the biological species. The biological species concept is accepted today.
The biological species concept explains that the group of interbreeding population that has the ability to reproductively isolated from the other such group.
Thus, the correct answer is option (c).
The correct answer is convection because the campfire warms the air around the person.
Convection refers to the transfer of mass motion of a fluid like water or air when the heated fluid is made to be carried away from the heat source, that is, carrying energy with it. Convection takes place when particles with an ample of heat energy in a gas or liquid move and occupy the place of constituents with less heat energy.
Heat energy is conducted from hot places to cooler places by the process of convection.
